Description
The M74HC280 is a high-speed CMOS 9-bit parity generator fabricated with silicon gate C2MOS technology.
   
Features
• High-speed:
    tPD = 22 ns (typ.) at VCC = 6 V
• Low power dissipation:
    ICC = 4 μA (max.) at TA = 25 °C
• High noise immunity:
    VNIH = VNIH = 28 % VCC (min)
• Symmetrical output impedance:
    |IOH| = IOL = 4 mA (min.)
• Balanced propagation delays:
    tPLH ≅ tPHL
• Wide operating voltage range:
    VCC (opr) = 2 V to 6 V
• Pin and function compatible with 74 series 280
• ESD performance
    – HBM: 2 kV
    – MM: 200 V
    – CDM: 1 kV
